What factors affect the lifespan of sliding windows?

The service life of sliding windows typically ranges from 15 to 30 years, depending on the following factors:

1. **Material**: Aluminum alloy windows are corrosion-resistant and have a service life of 20–30 years; thermal break aluminum windows can last over 30 years; PVC-coated steel windows last 15–25 years but are prone to aging in extreme temperatures; wooden windows last 15–20 years and require regular maintenance.

2. **Manufacturing Process and Installation**: High-quality craftsmanship and precise installation can extend the lifespan, while substandard products are prone to issues such as poor sealing and stiff operation.

3. **Environmental Conditions**: Humid, hot, cold, or coastal regions place higher demands on material weather resistance; harsh environments can accelerate aging.

4. **Maintenance**: Regularly cleaning the tracks, lubricating the rollers, and replacing the weatherstripping can reduce wear and tear and extend the lifespan.
